Dolang Technology Equipment Co.,Ltd.

DLLY-HYGS462 Constant Pressure Water Supply Training Equipment Constant pressure water supply training devices can meet the demand of constant pressure water supply,and keep the pressure at the ends (service pressure) in the water supply system pipeline network , the system can forecast setting pressure free,floe at the pumps high efficient area where the maximum lift and minimum lift. Through the pressure transmitter testing pipe pressure and translate into electrical signals sent to the controller, the controller compare,calculate and judge between pressure feedback signal and forecast setting pressure, to determine the operation frequency of frequency pump, one or more pump start-up and stop, so that the system can work normally and smoothly under various working conditions , in order to achieve the biggest energy saving effect. 1. The pressure transmitter: used for testing the constant pressure water tank port pressure, the pressure range that can be measured is 0 ~ 200 Kpa 2. Water level switch: perfect work of the pump, when water level is over-high or over-low increase water pump pressure, set to stop working. 3. Water tank completely protection: terminal set full outlet tube, the biggest limit is to protect the equipment. 4. Manual work drain-pipe : manual valve is used to send all water. 5. The input voltage: the three-phase four-wire, AC380 plus or minus 10% frequency 50 Hz / 60 Hz 6. Environmental temperature: 3 ℃ ~ 45 ℃ 7. Capacity: < 5 KVA Q1：What factors affect the price? A.
